Explanation: A single request is sent to the partner object.
If the partner is available, you can send a single request to the partner object.
If a reply is returned, the information is forwarded to the data area specified in
"DataOutput".
In terms of transfer sequences, there are priorities:
•
Lowest priority: TriggerInput
An active transfer triggered, for example, by "TriggerInput" on the sender
can be interrupted by a single request or a general request.
•
Medium priority: Single request
An active transfer triggered, for example, by "TriggerInput" on the sender
can be interrupted by a single request or a general request.
The interrupted or restarted request leads to a restart of the active
sequences without an error message.
•
Highest priority: General request
A general request can interrupt itself or a single request.
The interrupted or restarted request leads to a restart of the active
sequences without an error message.
The request interrupted or restarted by a single or general request leads to a
restart of the active sequences without an error message. If a sequence was
completed successfully, the "DataValid" status of the "DataStatus" output byte
remains set to TRUE.
The time taken for the response to the single request is evaluated by the
"MonitoringTime" parameter.
Note:
Consistency of the data output area across segments is only assured if the
receive sequence was completed successfully.
